Title Empirical analysis of passenger trajectories within an urban transport hub Type Conference Article
Year 2012 Publication ISCRAM 2012 Conference Proceedings – 9th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal ISCRAM 2012
Volume Issue Pages
Keywords Algorithms; Information systems; Trajectories; Urban transportation; Central stations; Data mining algorithm; Empirical analysis; Empirical data; Passenger movements; Simulation framework; Urban transport; Data mining
Abstract In this contribution we present an analysis of passenger trajectories in an urban transportation hub. We collected an extensive amount of empirical data consisting of both gate and individual stalking observation in the central station of Cologne. Three different data mining algorithms are used to analyze this data, producing both data that may be used as input for simulation frameworks, and, as an aside, visualizations of passenger movements that could be of high interest to transport and emergency managers. © 2012 ISCRAM.

Title Using mobile social media for emergency management – A design science approach Type Conference Article
Year 2011 Publication 8th International Conference on Information Systems for Crisis Response and Management: From Early-Warning Systems to Preparedness and Training, ISCRAM 2011 Abbreviated Journal ISCRAM 2011
Volume Issue Pages
Keywords Computer simulation; Information systems; Risk management; Crisis management; Design science; Large public events; Mobile social medias; Perceived ease of use; Perceived usefulness; Simulation studies; Social media; Design
Abstract Over the last couple of years social networks have become very popular and part of our daily lives. With the emergence of powerful smartphones and cheap data rates social media can now be accessed anytime and anywhere. Obviously, it makes sense to also facilitate social media for crisis management and response. In this contribution we present a system design for emergency support based on mobile social media with an emphasis on increasing security during large public events. We follow the design science approach as we provide an artifact design along with a description of its implementation and evaluate our artifact using the simulation study methodology. As a result of this study we gained valuable insight into how the users interact with our system and obtained information on how to improve it. Overall the users were quite satisfied with the perceived usefulness and the perceived ease of use of our system.

Title On the effectiveness of mobile service notification for passenger egress during large public events Type Conference Article
Year 2011 Publication 8th International Conference on Information Systems for Crisis Response and Management: From Early-Warning Systems to Preparedness and Training, ISCRAM 2011 Abbreviated Journal ISCRAM 2011
Volume Issue Pages
Keywords Benchmarking; Information systems; Agent based simulation; Broadcast messages; Evacuation strategy; Key performance indicators; Large public events; Mobile service; Passenger egress; Simulation; Mobile telecommunication systems
Abstract In this contribution we evaluate the effectiveness of mobile services for passenger egress of a train station during a large public event using an agent-based simulation approach. For this simulation we built a virtual replica of the Cologne central train station and collected empirical data on passenger numbers and their movements during a large public event. We simulate several different scenarios and compare the results using key performance indicators, such as time for egress. Our results show that dedicated cell broadcast messages under the described circumstances can be used to decrease evacuation time significantly and that the simulation can be used to quickly investigate the relevant key performance indicators needed to asses and evaluate the effectiveness of different notification and evacuation strategies.

Title Evaluation of a mobile emergency management system – A simulation approach Type Conference Article
Year 2010 Publication ISCRAM 2010 – 7th International Conference on Information Systems for Crisis Response and Management: Defining Crisis Management 3.0, Proceedings Abbreviated Journal ISCRAM 2010
Volume Issue Pages
Keywords Civil defense; Disasters; Information systems; Management information systems; Mobile telecommunication systems; Risk management; Systems analysis; Agent based simulation; Emergency management; Emergency management systems; Information delivery; Mobile communications; Mobile service; Multi-agent based simulations; Public events; Information management
Abstract Large public events such as sporting events, concerts, fairs and street festivals are quite common in metropolitan areas. Because of the high frequency of such events and the increasing number of involved parties, those being responsible for the organization and execution have to cope with increasing complexity and shortening time frames for planning and preperation. Because of the high concentration of passengers, unplanned incidents that occur during these public events can have devastating effects and can lead to crises and disasters. Emergency management systems that utilize mobile communication infrastructures can provide prompt information delivery to save human lives. In this paper we propose a system design for mobile emergency management and outline our approach of evaluating this system design using multi-agent based simulation. To make our simulation of passenger movements as realistic as possible we gathered empirical data for a large event as well as for normal rush hour traffic.

Title Interoperability for information systems in public urban transport security: The SECUR-ED interoperability notation Type Conference Article
Year 2012 Publication ISCRAM 2012 Conference Proceedings – 9th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal ISCRAM 2012
Volume Issue Pages
Keywords Information systems; Mass transportation; Unified Modeling Language; Urban transportation; Notation; Public transport; Secur-Ed; Security; Uml; Interoperability
Abstract In public transport and at large urban hubs, such as metro or train stations, transport operators and first responders collaborate in the prevention of and reaction to security issues. Within the EU demonstration project SECUR-ED a specific notation for interoperability of information systems in the domain of public transport security was developed. (In this context, the interoperability of actual operating systems is not the focus.) Based on UML (Unified Modelling Language), the notation language offers the possibility for structured modelling of system-of-systems architectures. Four interoperability object templates and their interdependencies form the underlying basis. Domain-specific annotation rules and guidelines for interoperability objects and their sub-component structures allow collaboration and interpretation of this model on various granularities and stages during a systems engineering process. © 2012 ISCRAM.

Title A concept for interoperability of security systems in public transport Type Conference Article
Year 2012 Publication ISCRAM 2012 Conference Proceedings – 9th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal ISCRAM 2012
Volume Issue Pages
Keywords Information systems; European research project; Heterogeneous communication; Heterogeneous information; Operational business; Public transport; Security; Shared understanding; System-of-systems architecture; Interoperability
Abstract In the field of public transport, operators and first responders collaborate in the prevention of and reaction to security issues. In order to optimise their specific daily operational business needs in a timely manner heterogeneous information and communication systems are deployed. In case of an incident however it is crucial that the various involved parties exchange relevant information to develop a shared understanding and act in a coordinated way. Yet, heterogeneous communication and information system infrastructures often hinder this crucial flow of information. To address this shortcoming it is crucial to enable the design of interoperable system-of-systems approaches in this domain. This paper describes a conceptual model to construct system-of-systems environments in the domain of security in public transport. By building on the results of several European research projects this concept offers a starting point for modelling and documenting individual systems inside a system-of-systems architecture. © 2012 ISCRAM.
